I've been reading this on and off and skipping some chapters in between 😭 Can someone t...

Not a novel reader but from what I have read months ago in a spoiler message, he’s being secretive with his phone because he’s caught in a really bad spot with the bottom’s mother.
At the start, the mother actually paid him to befriend the bottom so he wouldn't be lonely. But now, he’s genuinely in love with him. He's hiding his phone because the mother is still contacting him, and he knows if the bottom sees those texts or calls, he'll think their entire relationship was just a paid job and that he was being lied to the whole time. He's basically trying to handle/block the mother in secret so he doesn't break the bottom's trust.

OH MY GOD THIS IS ONE HELL OF A SPOILER SJJBXJHSID

wow, this totally invalidates all that stuff he says to the bottom about “i knew it was you in the beginning cause i remembered you all these years” he straight up lied and was actually told he was there by the mother. AND HE WAS BEING PAYED?? keeping a secret like that for so long is actually grounds for a break up cause let me find out you were lying to me for a year about some shit like that

Omg I knew there was something shady about him no matter how nice he seemed. I'd be so mad if I were MC

Thanks for the spoilers!!

ohhh nooo... ╥﹏╥ thats gonna break our bby bottom boy's heart

If Im not wrong (novel readers do correct me please if I’m wrong) it actually started back when Wooyeon was 16 in high school! His mother secretly hired Dohyun as a tutor to monitor Wooyeon's bullying and report back to her. College is where they reunite years later, and Dohyun is super secretive with his phone because he's trying to hide that his mom arranged the tutoring and is still contacting him

FUCK U RIGHT OH MY GOD

It's been so long since i read the novel so I might be remembering wrong but it does not really invalidates all he said. the initial contract ended the moment Yeon went to America since he was only paid to tutor him and report about the bullying back then. he also recognized him immediately after his friend said his name when they bumped the first time. this is what he meant by that line. Also Yeon's mother only contacted him again when he learned Yeon was enrolled in the same university as him and they were interacting again. The driver/butler also relays information to the mother who Yeon was meeting up iirc. before that, there were no contact between the mother and Dohyun when Yeon was in America. she hired another person to do that. He did not even know Yeon was back in Korea until he meet him again. The reason why Yeon's mom still has his contact and can contact him is because she sponsored him during his orphanage days and found him the family that adopted him.
